Help with my introduction paragrapgh please?

In November 2008 I was diagnosed with Angioedema. According to www.dictionary.com the encyclopedia definition of Angioedema is an “allergic disorder in which large, localized, painless swellings similar to hives appear under the skin. The swelling is caused by mive aculation of fluid (edema) following exposure to an allergen (a substance to which the person has been sensitized) or, in cases with a hereditary disposition, after infection or injury. The reaction appears suddenly and persists for a few hours or days, occurring most often on the face, hands, feet, , and mucous membranes.” There are two types of Angioedema; the first is Hereditary Angioedema (HAE) and second Acquired Angioedema (AAE). I will be explaining the difference between the two along with the causes, symptoms, and diagnosis for both.
